Ange mécanique sur mégapole cyberpunk

Cinematic sci-fi concept art of a colossal [machine angel girl] hovering above a dense futuristic megacity at night, shot from a dramatic low angle where she dominates the rainy skyline like a divine apparition. She features a sleek feminine humanoid body of white, silver, and graphite biomechanical armor, exposed segmented joints, filigree machinery, and glowing cyan circuitry across her torso, hips, thighs, and chest. Her face is a smooth, blank white mask partially in shadow, accented by a luminous cyan visor and a delicate metallic halo-crown. She has exactly 2 enormous outstretched wings of layered black, gray, and silver metallic feathers, each wing bearing exactly 1 glowing circular cyan techno-emblem at its center. Her pose is calm and solemn, arms relaxed at her sides, legs descending downward. Heavy rain, mist, floating atmospheric embers, and dark storm clouds parting with celestial backlighting surround her. Below, a vertical sprawling metropolis of dark skyscrapers with thousands of tiny window lights, haze, and wet reflective streets unfolds, with exactly 4 flying vehicles cruising through the air. Neon signs and East Asian typography illuminate the scene: a large red vertical sign reading "警戒" with small subtext "ALERT", a smaller red sign reading "緊急警報", a huge billboard reading "天使, 降臨。", and exactly 2 electronic billboards displaying her likeness. Color palette: cold steel gray, midnight blue, obsidian black, crisp white, and electric cyan with vivid red accents.
